CE> Hi Listmembers, CE> I'm rebuilding a polarimeter that needs a DS1497. I'm finding that's not CE> an easy device to obtain anymore. Seems they were discontinued in 1999.

CE> I'm open to suggestions. And the other question as always is.. is there a CE> pin-for -pin replacement? CE> Thanks for your time.
CE> Chuck The DS1487 is one of those CMOS clock + RAM + Li battery hybrid circuits in a 28 pin DIP package. According to MAXIM's website and other data on the net, a lot of those have gone obsolete, but it appears that the newer ones (DS12887) are pin-compatible replacements just with more memory and possibly year-2000 compliant. You should check with MAXIM directly - those folks normally are quite helpful! http://www.maxim-ic.com/appnotes.cfm/appnote_number/769/ln/en http://www.maxim-ic.com/TechSupport/QA/module.htm Uwe. -- Author: Uwe Zimmermann INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
